Discuss the Male Reproductive System The reproductive system is questionably the body system that is the most important influence on life as we know it. It is the w ay in which we procreate and ensure our existence as a species. However‚ the penis is only one part of the male reproductive system‚ which constitutes of a series responsible for generating‚ storing‚ and transporting the genetic material contained in the sperm cells. The main organs include: testicles (or testes)‚ the epididymides

CELL ULTRASTRUCTURE CELL ULTRASTRUCTURE Cells are the smallest functional units of the body‚ (Waugh‚ A. and Grant‚ A.2010). Most cells are microscopic. The largest cell in the body is the female ovum. The erythrocyte is the smallest cell. The longest cell is the neuron. Cells group together to form tissues‚ each of which has specialised function. Different tissues group together to form organs. Organs are group together to form organ systems‚ each of which performs a particular function that

scheme‚ algae are classified in seven divisions‚ of which five are considered to be in the Protista kingdom and two in the Plantae kingdom. The cell of an alga has eukaryotic properties‚ and some species have flagella with the “9‐plus‐2” pattern of microtubules. A nucleus is present‚ and multiple chromosomes are observed in mitosis. The chlorophyll and other pigments occur in chloroplasts‚ which contain membranes known as thylakoids. Most algae are photoautotrophic and carry on photosynthesis. Some forms
